Add move to SD
I know hundreds/thousands people have probably already sent this to you, but enable "move to SD card" for android. At this point, your application is useless to me because it lacks this feature on my tablet. I have a 128GB SD card sitting there with less than 2% used, in a 32 GB tablet, and can't synch my notebooks even though I have all that empty space, because OneNote insists on using 20-something GBs of my internal storage space. Without SD card functionality your app is straight up garbage for anyone who deals with large amounts of data or multimedia presentations.

There is already a post like that, but I'm voting here as well!

Absolutely crucial to be able to have the notebook cache stored on the SD card. I only have room for a current meetings notebook on my tablet and have to go back to my laptop for historical and reference notes.
